The results of systematic laboratory analysis and the interaction of minerals found in sample material from Antarctica could give scientists a better understanding of the surface area and the surface of Mars, and show its underground habitats, says a new paper by Planetary Science Institute Research Scientist. Elizabeth C. Sklute.

Samples of occasional brine extraction at Blood Falls at the end of Taylor Glacier, Antarctica, were compiled by Jill Mikucki of the University of Tennessee, Knoxville, for two seasons. Brine flows out of the groundwater, separated by thousands of years. The saltwater flow places material [which is] a reflection of the surface of the underground environment that hosts a thriving microbial community. At first, the brine is clear, but the deposit turns red over time, acquiring the name Blood Falls. These over-catching samples were tested in the Sklute laboratory using Fourier transform infrared, Raman, visible to nearby infrared, and Mössbauer spectroscopies. Samples were also observed using microprobe and inductively integrated plasma optical emission spectroscopy chemistry, X-ray diffraction, electron microscopy scanning, and electron microscopy for transferring mineralogy, crystallography, and chemistry.

“We took dry samples and analyzed them in the light of different wavelengths. The length of the light came and the bonds and atoms in the sample react differently. Using them together, we discover what they are,” said Sklute, lead author of “A Multi- Technique Analysis of Surface Materials From Blood Falls, Antarctica “from Frontiers in Astronomy and Space Science.

“We take these small pieces of information and glue them together to create a complete picture because one process might be too good to tell you if certain things exist and the other way might be completely missed, simply because bonds or atoms are connected.” Sklute. “These results demonstrate the strengths and weaknesses of different analytical methods and underscore the need for more coherent strategies to inform complex mineralogy in this area.

“By combining these mechanisms, we have determined the mineralogical synthesis of this analog Mars site and learned that deposits are usually carbonates and that the red color of Bloody Falls is due to the oxidation of molten ions (Fe2 +) ions as expressed. in the air, almost combined with other ions Instead of producing ferric minerals (Fe3 +), which are common on Earth, these salts turn into iron-containing nanospheres and a host of other nutrients, such as chlorine and sodium. amorphous have been found everywhere in Gale Crater on Mars by a Curiosity rover, “said Sklute. “So far, we have not been able to determine the exact composition of the amorphous material on Mars.

“We are not saying this is biosignature because it is not produced by microbes but rather chemistry where the bacteria live. However, it gives us a road map of the point of view of another frozen country,” Sklute said.
